Being responsible is actually not that difficult. I used to think it is hard to grow up into a responsible member of our society. An incident happening in a rainy Sunday afternoon changed my attitude. I was on my way to the bookstore and was waiting for the green light while a girl was knocked down by passing car, which drove off quickly. A man immediately gave his first aid and I had joined in without hesitation. Soon many help was given to the girl. Because we sent her to the nearest hospitals in time, she was able to receive properly treatment. Not badly injured, I expressed gratitude to those giving help. Compared with the escaping driver, I was proud of what I did.

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green £­ a strange world indeed.

Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called ¡°cones¡±. These help us to see in a bright light and to tell difference between colors. There are also millions of ¡°rods¡±, but these are used for seeing when it is near dark. They show us shape but no color.

Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

With brown curly hair and a pair of glasses, 19-year-old Nicholas Allegra from New York state, US, looks like a real-life Harry Potter. However, rather than waving a wand, Nicholas is a "wizard " at "jailbreaking ". This is probably why he ended up with an intern­ship at Apple, a job many of his fellow Brown University students dream of.

Jailbreaking is the process of removing the limitations set by Apple on devices with the iOS oper­ating system. These devices include the iPhone, iPod Touch, and iPad. It allows users to gain full access to the operating system and download additional materials that are unavailable through the official Apple App Store. However, it is estimated that Apple loses $100 million (640million yuan) from jailbreaking each year.

Nicholas, with a famous nickname "Comex", is the teenage hacker behind the jail-breaking site JailbreakMe. com. The site tells users how to unlock their iPhones using software that is not approved by Apple. The jailbreaking software he made has been downloaded millions of times by users around the world.

Then Forbes magazine suggested in an article that Apple's security team might need him as a new intern. It seems that they do. Little more than a day after Steve jobs stepped down as CEO, Apple welcomed Nicholas Allegra. Nicholas wrote on his Twitter on August 26 that " It's been really, really fun, but it's also been a while and I've been getting bored. So, the week after next I will be starting an internship with Apple.

Apple is not the only company embracing the skills of hackers. Facebook recently hired iPhone jailbreaker George "Geohot" Hotz as a full-time employee.

However, there are still hot debates about whether employing hackers is a wise solution. The word "hacker" has always had a double meaning. In the press, "hacker" means someone who breaks into computers. They steal from people's bank ac­counts, download sensitive information and attack legal websites. Among computer lovers, it means a cool pro­grammer who can make a computer do whatever he wants.

Hiring a hacker does have its advantages. A talented hacker is probably quite capable of finding problems and suggesting corrections. On the other hand, because of a hacker's former behavior, many people doubt their morals .Can the company trust them with its valuable assets ? And can someone who is so used to working alone in the dark fit into a new role within a company?

One thing is for sure- Comex isn't the first member of the hacker community to land the job of his dreams. It's likely that he won't be the last.

All around the world, people are working hard to make their cites safer and more pleasant for pedestrians (ÐÐÈË). Cities have painted crosswalks on their streets, made streets narrower, put in traffic lights and speed bumps (¼õËÙ´ø) and made plans to help more kids walk or bike to school.

Many people have learned from a man from Brisbane, Australia, named David Engwicht. His book Reclaiming Our Cities and Towns has a simple message. 1. Kids played there, and neighbors stopped there to talk.

But now, streets are just for cars and trucks. People stay inside to get away from the noise and dangerous traffic, and we lose contact with our neighbors. 2. People need to take back their streets. Engwicht travels around the world, helping people think differently about pedestrians, streets, and neighborhoods. 3. He has worked in neighborhoods from Honolulu to Scotland.

While Engwicht was writing his book, he learned how neighbors in the city of Delft, in the Netherlands, stopped dangerous traffic on their street. They put old couches, tables, and planters in the street. 4. When the police arrived, they saw how these illegal actions made the streets safer. Soon city officials started planning ways to make cars slow down, and¡°calm¡±the traffic.

Engwicht says we should think about streets as our ¡°outdoor living room¡±. 5.

In the future, streets will be safe places for children again, and our neighbors will become our friends.

A£®Cars and pedestrians crowded the street.

B£®Calming the traffic is just the beginning.

C£®Cars could still pass, but they had to drive slowly.

D£®He says that in the past, streets belonged to everybody.

E£®It¡¯s hard to take measures to solve the traffic problems.

F£®Besides his books and articles, he gives many speeches.

G. Engwicht says that we should use streets for more than just transportation.

Most people think about donating blood. However. Very few actuallv do it. Even the most consistent ones donate an average of just three to four times during their lifetime. Now the officials in Sweden are trying to change the trend with the help of modern-day technology.

The encouragement to donate again begins shortly after the donor leaves the clinic when he/she receives a "thank you" text. Though that certainly helps them feel appreciated, what is even more pleasing is the text they receive each time their blood is used to help someone in need.

Karolina Wiberg, manager of the Stockholm blood service, believes this small gesture not only results in repeat donors, but helps bring in new ones. The program that was started in Stockholm has received such positive feedback that it is now being rolled out across the country.

However, Swedish officials are not stopping there. They are also encouraging local clinics to publish the exact levels of the different blood groups they have at any given time on their websites. This allows potential donors to realize that their blood can make a difference in saving someone ' s life.

While all these outreach programs are great, busy citizens, even the ones with the best intentions have to be occasionally reminded. In order to jog their memories, officials ask people for authorization to send them text, Facebook, and e-mail reminders. Though that may sound disturbing, the citizens do not seem to mind, given that the messages are light-hearted and fun-things like "We won't give up until you bleed."

Though Sweden is currently the only country using modern technology to urge more donations, don't be surprised if more join in, especially if the Nordic (±±Å·) country's blood banks start to overflow!

A. To ask them for authorization.

B. To inform them their blood is used.

2.What does "the program" in paragraph 3 refer to?

A, Publishing information about blood donation.

B. Giving Facebook reminders to citizens.

C. Sending text messages to blood donors.

D. Providing people with blood service.

3.What do people think of blood donation reminders?

A. Disturbing. B. Memorable.

C. Authentic. D. Acceptable.

4.What can we infer from the last paragraph?

A. Sweden will stop urging blood donation.

B. Sweden has benefited little from its program.
